if someone figures this out i'll shit

i have posted this several times and never get any answeres

problem 1) the car does not start right up when it is cold unless i turn the key to on and back to off about 4 times and let it sit on on for 5 seconds

problem 2) the car runs rich as hell it slowly gets richer the higher the rpm it goes from .98 at 2.5k to 1.06 at 6.5k and slowly richins all through the revs)

problem 3) it pulls decent in first gear, second gear it starts to suck, 3 gear sucks more, 4 sucks more, and fith even more

problem 4) i seem to hit fuel cut even at 11 psi

problem 5) everytime i ask what to look for when datalogging noone answeres, what should my fuel trims be and what should my mafs read

problem 6) i need something so i can post my datalogs on here

change your fuel pressure regulator and also the FPR solenoid.

problems 3 and 4 could be boost leaks......check for those if you haven't already. problem 1 sounds like a fuel problem, possibly bad fuel pump? since the fuel pump turns on when you turn the key, maybe its clogged up or the fuel filter is clogged and not getting any fuel to the motor. try just typing up your logs, i know it will take awhile but we can help more if we see a log. i'm almost positive problem 4 is a boost leak, my friend (thomas91169 on here) had the same problem.....

my fuel pump is brand new and i replaced my fuel filter a year ago so it should be fine.

does you thing a leaking injector could be the problem instead of the fuel pressure regulator? how to i test my fuel pressure regulator?

what do you want me to moniter during my datalog? which gears? which sensors?

You test the FPR by putting another one on from a known running car. It takes a whole 5 minutes to swap em. Same goes for the solenoid. Just gotta start trying everything.

It could be any of those. Or it could be a vacuum leak somewhere. If your still using maf the computer is not going to see that extra air coming in through a vacumm leak. Therefore dumping extra fuel into the combustion chamber.

1st I would start off by making a boost leak tester and pressurize your piping system to see if you could hear air leaking out somewhere in the system. Then I would investigate the fuel pressure regulator and so on.

You can make a pressure tester out of $5 worth of parts from lowes. If you have a air compressor then you're set, if not, borrow one from a friend. Using a pressure tester will save you from trying lots of mystery fixes.

This all seems to point to the fuel pump.....

Log between 3rd and 4th gears at WOT. Your fuel trims ideally would be at 100%, but every car is different.

Anything above that the ecu is richening up the mixture, below that it's leaning it out. Log RPM's, TIMA (timing advance), O2, FTRM and FTRH.

And check for boost leaks. You're hitting fuel cut because your turbo is pulling more air than it normally should because of leaks. The boost gauge sees 11psi, but your MAF is seeing more than that and when it's done calculating everything it thinks it's hitting 20 or so psi.
